In computing, virtualization is often used to create a virtual version of a hardware platform, an operating system (OS), storage devices, or network resources. Virtualization is also often used to improve the effective utilization of a server's physical resources. A variety of techniques have been used to manage virtual resources. For example, virtual resources, such as virtualized data centers, have been managed by using non-work conserving or work conserving approaches. For the non-work conserving approach, each workload is provided with restricted access to resources that can be used per time interval. The non-work conserving approach may be referred to as a resource capped mode. Thus, for the non-work conserving approach, in order to guarantee workload isolation, the sum of the caps for each resource are set to be less than the overall available capacity for all resources. For the work-conserving mode, a workload may use the excess capacity that is not used by other workloads. The work-conserving approach may be referred to as a non-capped mode. Compared to the non-work conserving approach, the work conserving approach often leads to higher resource utilization.
